Could the mystery surrounding the "plague of flies" reportedly dominating the skies of Dublin 4 suburbs be solved?

Last night, the Environmental Protection Agency said it undertook a site visit to Poolbeg Incinerator - operated by Dublin Waste to Energy Ltd - on foot of complaints and reports concerning swarms of flies in the neighbouring Irishtown and Ringsend areas.

"The inspector found moderate fly numbers in the waste intake building and bunker area. Dublin Waste to Energy Ltd has had a pest control contractor on site on the 2nd, 5th and 6th of July to undertake fly control.

"The EPA has instructed Dublin Waste to Energy Ltd to continue fly treatment, as necessary, to ensure that fly populations do not increase on site," a statement from the EPA said.

The EPA has promised to monitor the situation.

Response

The site visit came after Labour Senator Kevin Humphreys complained about a "plague of flies" on his Facebook page.

The post was inundated with comments from residents with similar tales of woe.

"It's been going on for the last three or four days," said Labour Senator Mr Humphreys.

"We asked [on Facebook] how many people were experiencing problems with the flies and we were inundated with people saying they were being driven demented."
